博乐市玉米秸秆腐熟剂应用效果试验结果表明,秸秆+腐熟剂和秸秆还田均可以提高穗粒重,进而显著增加产量。使用腐熟剂较秸秆单独还田增加产量643.5 kg/hm~2,增幅4.8%。秸秆直接还田与腐熟剂配施可以显著提高土壤有机质、碱解氮、速效磷、速效钾的含量,降低土壤容重。使用秸秆腐熟剂可以显著提高土壤酶活性,促进有机质的积累,提高矿质养分的有效性。
The results of application of corn stalk composting agent in Bole City showed that straw + maturity and straw returning could increase the grain weight per ear and significantly increase the yield. The use of decomposing agent alone increased straw yield 643.5 kg / hm ~ 2, an increase of 4.8%. The direct straw returning and composting could significantly increase the contents of soil organic matter, available nitrogen, available phosphorus and available potassium, and reduce the soil bulk density. The use of straw maturity agent can significantly increase soil enzyme activity, promote the accumulation of organic matter and improve the effectiveness of mineral nutrients.
